摘要： An apparatus improves rotation of a rotatable shaft. The rotatable shaft has a cyclical cogging torque acting thereon in a first direction. The apparatus includes a support member, first and second anti-cogging members, a cam surface and an abutment member. The support member is adjacent the rotatable shaft. The rotatable shaft is operable to rotate relative to the support member. The second anti-cogging member is coupled to the rotatable shaft for rotation with the rotatable shaft. The cam surface is included on one of the first anti-cogging member and the second anti-cogging member. The abutment member is coupled to the other one of the first anti-cogging member and the second anti-cogging member. The abutment member is operable to abut against the cam surface to provide an anti-cogging torque to the rotatable shaft in a second direction that opposes the first direction to at least partially offset the cogging torque.

摘要： A high-pressure pump (8) for providing a pressurized supply of fuel in an engine furnished with a common rail type fuel injection apparatus is provided with two actuators (88, 89). Of these actuators (88, 89), one (88) is stopped and the operation for providing a pressurized supply of fuel is performed from only the other actuator (89), so that the timing at which the load torque that acts on the crankshaft of the engine becomes a local maximum and the timing at which the load torque that acts on the driveshaft of the high-pressure pump (8) becomes a local minimum are made to coincide with one another.

摘要： A standard cam phasing OCV may be employed as a virtual check valve to choke the backflow of oil during negative cam torque conditions, including execution of a duty cycle command in an event-based manner. Normally, OCV duty cycle commands are made on a time basis, but for VCV the duty cycle output change must be synchronized with engine events. A method is disclosed for calculating and delivering the VCV duty cycle so that both time-based and event-based controls are maintained and work together. Phase alignment of response time of the OCV solenoid is based upon cam target wheel edges and is event-based. An initial phase rate vs. phase angle is monitored by the Engine Control Module (ECM). Adjustment of the phase angle is provided to achieve maximum cam position phase rate.

摘要： A system for continuously varying actuation of a valve in an internal combustion engine including a first cam for opening the valve, a second cam for closing the valve, and an oscillating rocker arm continuously engaging each of the first cam, the second cam, and the valvetrain, with the aid of a lost motion spring. The cams are disposed on first and second camshafts that are geared together. The first camshaft gear is driven by the engine crankshaft and thus is phase-invariant. The second camshaft gear is rotationally mounted on the second camshaft and supports the stator of a camshaft phaser. The phaser rotor is mounted to the second camshaft. Varying the rotor position varies the phase of the second cam and thus varies lift and closing timing of the valve. The system is useful in improving the performance of both spark-ignited and compression-ignited engines.
